The Aircraft Communications Addressing and Reporting System (ACARS) very high frequency (VHF) link is designed to be a subnetwork used by various entities including aircraft, airlines, air traffic control, and the like for communications. In particular, an ACARS VHF link is used to exchange datalink messages (for example, Air Traffic Control (ATC), Airline Operational Communications (AOC), etc.) between an aircraft and a ground station or other end system equipment.
